ARP AVATAR with Mods

" 1. MIDI by synhouse.com, (The CV inputs also work if you want to go full OLD-SCHOOL.)

2. FILTER UPGRADE
Avatar filters have a upper frequency limit of 11khz! This frequency response upgrade is similar to the 2600 filter upgrade extending the cutoff frequency range from 11khz to 28khz. Also replaces some critical components in the signal path. Your filter sub module is removed, tested, upgraded, re-tested and re-installed into main board "C".

3. AUDIO PATH UPGRADE
This mod replaces critical signal path components with audiophile grade components. Low end response is improved resulting in a more accurate wave shape. This mod used to be called the "Low end wave correction mod" in the early days of CMS. High end response is also Improved.

4. POWER SUPPLY REBUILD
Certain critical components in your power supply have a shelf / working life of 20 years maximum. It's probably time your power supply was rebuilt. These units are getting very old, so if you are serious about your ARP, you should get the Power Supply Rebuild.

5. PORTAMENTO ENABLE
Stock Avatars have their portamento circuits hardwired to the guitar section. This mod rewires the portamento so that it slews the keyboard cv input. (MIDI works too)

Please note: The guitar functions of the avatar have are disabled and/or removed. So, no pickup, guitar cord, or guitar board, is included with the synth. Why would you want that anyway! Avatars are prized for the synthesizer section, which is fully functional. Cosmetically, there are some corner dings, and some front panel scratches (partially repaired to prevent corrosion of the steel case). These are illustrated in the photos. However, the inside is clean, and all the sliders have been cleaned and re-greased. No slider caps are included, as is common for the avatar, but they are easy to find on ebay, or from CMS if you want a set."
